Factory Supply Irgacure 651, also known as Benzil Dimethyl Ketal, has the CAS number 24650 - 42 - 8. It is a high - quality photoinitiator with a best price in the market. The chemical formula of Benzil Dimethyl Ketal is C16H16O3. It appears as a white to off - white crystalline powder.
The melting point of Irgacure 651 ranges from 65 - 67°C. It is soluble in most common organic solvents such as toluene, acetone, and ethyl acetate. This product is designed to be highly efficient in initiating the polymerization of unsaturated prepolymers and monomers under UV light irradiation.
Irgacure 651 finds wide applications in various industries. In the coatings industry, it is used to formulate UV - curable coatings. These coatings can be applied to wood, metal, plastic, and paper substrates. The UV - curable coatings offer excellent hardness, abrasion resistance, and chemical resistance, which are highly desired properties in industrial and decorative applications.
In the printing industry, it serves as a key component in UV - curable inks. UV - curable inks dry almost instantaneously when exposed to UV light, allowing for high - speed printing processes. This leads to increased productivity and improved print quality, as there is no risk of smudging or offsetting.
It is also used in the adhesives industry. UV - curable adhesives based on Irgacure 651 provide strong bonding between different materials, and they can be cured rapidly, which is beneficial for assembly lines in manufacturing.
When using Factory Supply Irgacure 651, it is important to follow proper procedures. First, it should be added to the formulation at an appropriate concentration. Generally, the recommended dosage ranges from 1% to 5% by weight, depending on the specific application and the formulation of the prepolymer and monomers.
The product should be thoroughly mixed with the other components in the formulation to ensure uniform distribution. Once the formulation is prepared, it can be applied to the substrate using conventional coating or printing methods, such as spraying, brushing, or roller coating.
After application, the coated or printed substrate should be exposed to UV light. The UV light source should have an appropriate wavelength and intensity to ensure efficient curing. The exposure time also needs to be carefully controlled to achieve the desired curing effect.
Case 1: Wood Coating
A furniture manufacturer wanted to improve the durability and appearance of their wooden furniture. They decided to use a UV - curable coating formulated with Irgacure 651. The coating was applied to the wooden furniture using a spraying method. After exposure to UV light for a few seconds, the coating was fully cured. The resulting finish on the furniture was hard, scratch - resistant, and had a high - gloss appearance. The production time was significantly reduced compared to traditional solvent - based coatings, and the environmental impact was also minimized.
Case 2: Printing on Plastic
A packaging printing company needed to print high - quality graphics on plastic containers. They used a UV - curable ink containing Irgacure 651. The ink was printed on the plastic containers using a flexographic printing process. The UV - curing system in the printing press allowed for instant drying of the ink, enabling high - speed printing. The printed graphics had excellent color saturation, sharpness, and adhesion to the plastic surface.
